Apple's iPhone 5S is far ahead of its cheaper sibling -- the 5C -- when it comes to sales in Britain.

According to a new report from The Telegraph, the iPhone 5S is outselling the 5C by a ratio of three-to-one. The 5S is Apple's latest high-end iPhone release that launched in September for an unsubsidized starting price of $650. The 5C starts at $550.

But this doesn't necessarily mean that the 5C was a bust for Apple. In fact, the report noted that the 5C has been acting like an iOS starter kit for those coming from other mobile operating systems like Android and Windows Phone.

The report also noted that the 5C is attractive to households with lower incomes (less than $49,000).

Apple is making some headway in the UK, but it still trails behind Android. Android's market share in the UK is 56 percent while Apple's iOS sits in second place with 29 percent. Windows Phone is in third place with 12 percent and BlackBerry is in last place with 3 percent.
